Background/Objectives: Osteoporosis is a major public health concern, due to its high risk of fractures and disability and associated medical costs. Romosozumab, an anabolic agent, has been approved for the treatment of osteoporosis in postmenopausal women at high risk of fractures. However, limited data exist on its long-term effects in the Korean population, particularly regarding its impact on bone mineral density (BMD), bone turnover markers, and body composition. This study aimed to evaluate the 12-month effects of romosozumab treatment on BMD, bone turnover markers, and body composition in postmenopausal Korean women with high-fracture-risk osteoporosis (T-scores ≤ −3.0). Additionally, the impact of concomitant postmenopausal hormone therapy (MHT) on BMD changes was assessed. Methods: This multicenter, retrospective observational study included 50 postmenopausal women diagnosed with osteoporosis (T-scores ≤ −3.0) who received 12 monthly doses of romosozumab (210 mg) at two hospitals in Korea. Changes in BMD in the lumbar spine, femoral neck, and total hip were assessed using dual-energy X-ray absorptiometry (DXA). Bone turnover markers, including procollagen type 1 N-terminal propeptide (P1NP) and C-terminal telopeptide of type 1 collagen (CTX), were measured at baseline and at 3, 6, and 12 months. Changes in body composition, including the skeletal muscle index (SMI), body mass index (BMI), and visceral adipose tissue (VAT), were also analyzed. Results: After 12 months of romosozumab treatment, BMD significantly increased at the lumbar spine (14.65%), femoral neck (6.58%), and total hip (4.19%) (p < 0.05). P1NP levels increased significantly at 3 months (+37.9%), but returned to baseline at 6 months, while CTX levels continuously decreased (−27.8%) over 12 months. No significant changes were observed in SMI or BMI, but the VAT showed a slight decreasing trend (p < 0.05). Additionally, patients receiving concomitant MHT demonstrated a significantly greater increase in lumbar spine BMD compared to those receiving romosozumab alone (p < 0.05), while no significant differences were observed in femoral neck and total hip BMD. Conclusions: This study demonstrated that 12 months of romosozumab treatment significantly improved BMD and bone turnover markers in postmenopausal Korean women with severe osteoporosis. The combination of romosozumab and MHT further enhanced lumbar spine BMD gains. These findings support the use of romosozumab as an effective treatment for high-risk osteoporotic fractures in postmenopausal Korean women, and suggest potential benefits of a combined therapeutic approach.

Globally, the incidence of gastric cancer is lower in women than in men. It is thought that menstrual and reproductive factors may be related to their lower incidence of gastric cancer. This cross-sectional study examined menstrual, reproductive, and other factors in 20,784 postmenopausal women from the 2007–2020 Korea National Health and Nutrition Examination Survey (KNHANES). A univariate logistic regression analysis was performed, and then a multivariate logistic regression analysis for significant factors in the univariate analysis was conducted. In the multivariate logistic regression analysis, the age at menarche (odds ratio [OR] 1.08, 95% confidence interval [CI] 1.00−1.06, p = 0.035) and myocardial infarction (OR 2.43, 95% CI 1.05−5.62, p = 0.026) showed a significant association with increased incidence of gastric cancer. The age at menopause (OR 0.97, 95% CI 0.95−1.00, p = 0.03), the age at the first childbirth (OR 0.93, CI 0.89−0.97, p = 0.007), and the experience of alcohol consumption (OR 0.68, 95% CI 0.5–0.91, p = 0.003) showed a significant association with a decreased incidence of gastric cancer. Late menarche, early menopause, early aged first childbirth, and myocardial infarction are estimated to be risk factors for gastric cancer in postmenopausal Korean women.

Background and Objectives: Body composition changes with aging and menopause, often leading to increased adiposity and a shift in fat distribution. While BMI is commonly used in clinical practice, it does not accurately reflect fat mass or distribution. This study aims to evaluate age-related changes in both total and regional adiposity using DXA-derived indices in Korean women aged ≥ 40 years and to assess the limitations of BMI-based obesity classification. Materials and Methods: This retrospective multicenter study analyzed the DXA scans and clinical records of 914 Korean women aged 40–80 years who attended menopause clinics across multiple institutions between 2018 and 2021. We analyzed five adiposity indices: body mass index (BMI), total body fat percentage (TB%F), fat mass index (FMI), visceral adipose tissue (VAT) area, and android-to-gynoid (A/G) fat ratio. Excess adiposity was defined as BMI ≥ 23 kg/m2, TB%F ≥ 40%, FMI ≥ 9 kg/m2, VAT > 100 cm2, or A/G ratio > 1.0. Age group comparisons were made using ANOVA, and misclassification was assessed by comparing BMI with other indices. Results: Mean BMI increased with age, peaking in the 60s before declining in the 70s. TB%F and FMI peaked in the 50s, while VAT and A/G ratio increased continuously with age. Excess adiposity was found in 41.9% of women by TB%F, 40.5% by FMI, and 59.4% by VAT in the 70s. Notably, 22% of women with normal BMI ( 100 cm2, and 35.7% had A/G > 1.0, indicating central obesity. Conclusions: DXA-based indices provide a more accurate assessment of adiposity and associated cardiometabolic risks in aging women than BMI alone. Clinical screening strategies should consider incorporating regional fat distribution markers, particularly in midlife and postmenopausal populations, to better identify individuals at risk.

Background/Objectives: Uterine leiomyomas are the most common benign gynecological tumors in women of reproductive age and are often associated with localized symptoms. However, emerging evidence suggests a link between uterine leiomyomas and systemic conditions such as cardiovascular disease (CVD), particularly myocardial infarction (MI) and ischemic stroke (IS). This study aimed to investigate the relationship between uterine leiomyomas and the risk of CVD events in young women aged 20–39 years using a large, nationwide, population-based cohort. Methods: This retrospective cohort study analyzed data from the National Health Insurance Service database of South Korea of 2,581,700 women aged 20–39 years who underwent health screening between 2009 and 2012. Uterine leiomyomas were identified using International Code of Disease, 10th Edition codes. CVD events (MI and IS) were defined according to hospital claims and radiological data. Multivariate hazard ratios (HRs) were calculated to evaluate the association between leiomyomas and CVD after adjusting for confounders (age, lifestyle factors, comorbidities, and body mass index). Results: In all, 58,812 were diagnosed with uterine leiomyomas, and 25,063 underwent surgical treatment. During the follow-up period, MI occurred in 115 women (0.21%) and IS in 82 women (0.15%) in the leiomyoma group, compared with 3107 cases of MI (0.12%) and 2240 cases of IS (0.09%) in the non-leiomyoma group. The leiomyoma group demonstrated a higher incidence rate of CVD (IR: 0.63 vs. 0.39 per 1000 person-years). After adjusting for confounding factors such as age, lifestyle, comorbidities, and body mass index (BMI), the hazard ratio (HR) for MI was 1.32, indicating a statistically significant increase in cardiovascular risk. The risk of CVD was lower in women who underwent surgical treatment; however, when specifically analyzing the occurrence of MI and IS, no statistically significant differences were observed between the two groups. Conclusions: Uterine leiomyomas are associated with an increased risk of MI and IS in young women. Surgical treatment itself may be associated with additional cardiovascular risks. Further research is needed to develop strategies to mitigate these risks and elucidate the underlying mechanisms.

Background and Objectives: Osteoporosis is a common chronic condition after menopause that increases the risk of fractures. In South Korea, the prevalence of osteoporosis among adults aged 50 and older is 22.4%, with 94.4% of treated patients being women, highlighting its significant impact on postmenopausal health. In this study, we examine the sales trends of osteoporosis medications in Korea from 2018 to 2023 to understand current usage patterns and market dynamics. Materials and Methods: This study is a retrospective analysis based on pre-recorded sales data from Intercontinental Marketing Services (IMS). Data covering a five-year period (2018–2023) were analyzed to examine the sales trends of osteoporosis medications, including bisphosphonates, selective estrogen receptor modulators (SERMs), parathyroid hormone analogs, denosumab, romosozumab, and others. Romosozumab, approved in November 2019, was included in the analysis. Given the nature of this study, no direct patient data or clinical interventions were involved. Results: The total market size for osteoporosis medications in South Korea reached USD 285.42 million in 2023, reflecting a 15.3% increase from 2022. Bisphosphonates, previously the dominant therapy, experienced an 11% decline in market share over five years. Meanwhile, denosumab, a receptor activator of the nuclear factor-κB ligand inhibitor, showed a remarkable growth rate of 957.6% from 2018 to 2023, surpassing bisphosphonates in their market share. Romosozumab, a newly introduced anabolic agent, accounted for 7.4% of the market, with sales increasing by 59% in 2023. Conclusions: This analysis revealed major shifts in treatment preferences, with newer drugs like denosumab and romosozumab gaining prominence over traditional bisphosphonates. These trends highlight the increasing clinical adoption of anabolic agents for high-risk patients and the impact of expanded reimbursement policies on osteoporosis management. Given the increasing use of advanced therapies, it is essential to monitor treatment access, patient adherence, and long-term clinical outcomes. Understanding these sales trends can aid healthcare professionals and policymakers in optimizing osteoporosis treatment strategies and ensuring better patient care.
